A. Uxinaniso oluphantsi: ngenxa yomsantsa phakathi kwamatyathanga emolekyuli, inani leemolekyuli kwiyunithi nganye umthamo lincinci, elimisela iingenelo zelensi ye-resin: ubunzima obuphantsi obuthile kunye nokukhanya okukhanyayo, okuyi-1/3-1/2 ye iglasi yeglasi;
B. I-moderate refractive index: eqhelekileyo i-CR-39 propylene diethylene glycol carbonate, i-refractive index yi-1.497-1.504.Okwangoku, isalathisi esiphezulu se-refractive index of resin lens ezithengiswa kwi-market ye-glasses ye-Shenyang yi-aspherical ultra-thin hardened film resin lens, i-refraction Izinga lingafikelela kwi-1.67, kwaye ngoku kukho iilensi ze-resin kunye ne-refractive index ye-1.74.
C. Ubunzima bomphezulu bungaphantsi kunobeglasi, kwaye kulula ukukrwelwa zizinto eziqinileyo.Ngoko ke, kufuneka iqiniswe.Izinto eziqiniweyo ziyi-silica, kodwa ukuqina akulunganga njengokuqina kweglasi.Ngoko ke, umntu onxibayo kufuneka anikele ingqalelo kwi-lens.ukugcinwa;
D. I-elasticity ilungile.Ngenxa yesithuba phakathi kwamatyathanga e-organic molecular, i-elasticity yi-23-28 amaxesha e-glass piece.Olunye uphawu oluphambili lwephepha le-resin lichongiwe - ukuchasana kwempembelelo efanelekileyo.Amazwe aseYurophu, eMelika, naseJapan abalela abantwana abangaphantsi kweminyaka eyi-16 ukuba banxibe iilensi zeglasi;
E. Umsebenzi oncedisayo: Ingongezwa ukufumana imisebenzi efana nokuthintela imitha eyingozi kunye nokuguquka kwebala.
